The hybrid composite PW11Co/PAMAM was characterized by FT-IR, UV-Vis diffuse reflectance spectra, XPS, XRD and TG/DTA, indicating that the PW11Co was chemically anchored to PAMAM. The morphologies of the title composite were characterized by scanning electron microscopy and transmission electron microscopy. The catalytic activity was evaluated by oxidation of isobutyraldehyde to isobutyric acid in MeCN under mild conditions (20 ℃, ambient pressure), showing that the title compound is a more effective and recoverable catalyst than corresponding PW11Co.
